The Log in the Mill. 

 Coming to the mill, the logs are 

 divided into size and quality, those 

 most suitable for saw logs going in- 

 to lumber and the smaller unsound 

 or crooked logs going into pulp 

 blocks and then ground into wood 

 pulp by means of grinders or cut in- 

 to chips to be cooked by chemical 

 means into pulp. The sawing of the 

 logs into either lumber or pulpwood 

 is done with 3/16" band saw instead 

 of the quarter inch circular saw 

 formerly used, which saves in the 

 width of the saw scarf, enough 

 wood to represent many cords per 

 day. A band saw also leaves a 

 smooth cut end instead of a rough 

 abrased end, which is an advantage 



and saving when the pulp blocks are- 

 cut into chips. In the saw mill all 

 spruce, fir and hemlock waste in 

 sawing, such as slabs, edgings, and 

 butt ends, are run through a hogging 

 machine which converts them into- 

 chips. The remaining waste from 

 pine and cedar together with the 

 saw dust and bark is carried by con- 

 veyors into the boilers as fuel. 



Cooking Oil Produced. 

 In the changing of logs into lum- 

 l)er and paper many by-products of 

 unusual forms appear. The spruce, 

 fir and hemlock lumber either goes 

 into house frames, clapboards, 

 I)iano stock, cross-arms for tele- 

 graph and telephone poles chemi- 

 cally treated to prevent their rotting, 

 piling and timber for wharfage 

 soaked in corrosive sublimate as a 



Brush carefully piled on Timber Sale at Clinton. B.C., in the Dry Belt, in 



readiness for burning.
